PURPOSE:To switch automatically connection to each measuring vessel by connecting a selected flow passage of a flow passage selection switching part, a flow passage of a fuel vessel, and a flow passage of an engine system to a three-direction switching part to detect passage of a vehicle at a base point on a circular path. CONSTITUTION:During running, the vehicle steps on a tape switch 61, and a light emitting body 63 emits light at this instant, and this light reaches a light receiving body 64 to generate an output change, and it is sent to a control part 53. The control part 53 transmits a prescribed driving signal to a driving motor 52 in accordance with the input coming to the control part 53, and the motor 52 is turned at a prescribed angle to connect a flow passage 11 of the first measuring vessel 10 and a selected flow passage 54. Simultaneously, a switching signal is transmitted to a three-direction switching part 6 from a switching control circuit of the control part 53 in accordance with the first coming input, and flow passages 4 and 3 are cut off, and flow passages 4 and 54 are connected. Thus, fuel is supplied to an engine from the measuring vessel 10 while the vehicle circulates. |
